在WPF C#中隐藏DataGrid上DataTable中的行 [英] Hide rows from DataTable on DataGrid in WPF C#

问题描述

我试图从DataTable中隐藏特定的行，但是我只能隐藏列.

I'm trying to hide specific rows from DataTable, but I'm only able to hide columns.

我找到了一些与DataGridView相关的解决方案，但这并不相同，因此对我不起作用.

I found some solutions related to DataGridView, but it's not the same and didn't work for me.

在我的xaml文件中，我有:

In my xaml file I have :

<DataGrid Visibility="Visible" HorizontalAlignment="Stretch" Name="dataGrid_first" VerticalAlignment="Stretch" Width="Auto"  Grid.Column="1" Grid.Row="2" >

</DataGrid>

要在其上显示数据，我正在执行以下操作:

To show data on it, I'm doing as follows:

dataGrid_first.ItemsSource = myDataTable.AsDataView();

它正在工作.为了隐藏列，我正在做这样的事情:

And it's working. To hide columns, I'm doing something like this:

dataGrid_first.Columns[i].Visibility = Visibility.Hidden;

其中"i"是正确的列号.

where 'i' is proper column number.

如何隐藏行?

推荐答案

我也建议您进行过滤，而且我将不再使用DataTable.您可以使用

I would recommend filtering as well, and more I would not use DataTable a bit old. You can hide row with

<DataGrid ItemsSource="{Binding DataView}">
                <DataGrid.RowStyle>
                    <Style TargetType="DataGridRow">
                        <!-- your column name, visibility was not working if there is no converter -->
                        <Setter Property="Visibility" Value="{ Binding Path=IsVisible ,Converter={StaticResource BoolToVisibilityConverter}}"></Setter>
                    </Style>
                </DataGrid.RowStyle>
            </DataGrid>

在您的ViewModel中

In your ViewModel

myDataTable.Rows[i]["IsVisible"] = false;

如果未设置DataContext，则组件将成为上下文，因此可以在其中添加DataView属性(但可以的话，请使用ViewModels). BoolToVisibilityConverter

If you don't set a DataContext your component will be the context so you can add DataView property there (But use ViewModels if you can). BoolToVisibilityConverter
